T0 all wi'wm zlt mwy conc-ern:

.Be i knownithat we, GUSTAVE WENZEL- '1'HANN and EDWARD H. OVERHOLT, oitizens of the United Stabes, and residencs of Streator, Lasalle oounty, Illinois, have invei1ted 0er- -tain new and useful Improvements in Elevators 01 Jacks; and we do hereby deolare that the following is a full, clear, and exaot description of the same, reference being had 120 the aocompanying dra wings and to the lettexs of reference 1n2nked thereon, which form a pert 01 this specifioation.

This invent1on relates more partioularly to a wagen elevator o1 jaok adepted to elevate the frontend of a loaded Wagon 01' the like to deliver the contents from alle rear end thereof into a reoeiving-hopper for ehe purpose of unloeding the wagen. Heretofore jacks 'or elevators fo 1 the purpose described have frequently operated-by a sorew-feed or/che like and have therefore been slow in operation in elevating the load and of course equally slow in lowering the 'unloaded Wagon. F urlzher- 1nore, it l1as been an objecoion eo many of the devices of ehe kind that in elevating the front end of the Wagon the carriage rises vertioally of necessiy, drawing the Wagon some- What forwardly.

T he objeoo of this invention is to provide a cheap, strong, simple, and durable jack notreadily gotten out 0f order. and so construoted as to gelevate the load quiokly and to even mo1e quickly return the Wagon to a horizonaal p'osition. lt is also an objeot of the invention to so construct the jaok that the car ringe on which the fiont wheels of ehe wagen rest moves slightly nearwardly es well es up wardly in elevating, so that the front wheels ofthe wagen in the upward movement de s'cribe an arch with ehe rear a'xle es a center.

The invention oonsists in the 1natters hereinafter described, an'd more fully pointed out and defined in-the appended cla-ims.

In the draWirigs, F1gure 1 is n top plan view of a device embodying our invention. Fig. 2 is a Side elevation thereof. Fig. 3 is an enlarged longitudinal vertioal section of the 'tumbling-rod and main-shaft couplingand n1eans operating the same. 4 is a sec tion taken 011 line 4- 4 of Fig. 3.

Fig. M is an enlarged side elevation of the hoistingehain W.ith th.e adjustable stop thereon. Fig. 15is a sixnilat view taken at a right angle with ahnt shown inFig. 14. Fig. 16 is a section haken on line 16 16 ofFig. 3. Fig.'l7 is a fragmentary de teil of' the gear and one of the .braokets bearing againso thesarne.

As shown in said drawings, seid ja:ok o1 elevator comprises a strong rectangular fl'zL1l-10- comprising sills A and A, disposed laiemlly of 'the driveway, and -tothe front ends of which is rigidly bolted a plank a, which affords an.inclined driveway fro1n the deck. Planks a a? are bolted a1; the rear ends of the sills and aflord a strong de'ck for supporting the hont end of the Wagon, and joists o1 supporbs (shown in dgited lines in Fig. l) a1e se cured beneath said deck. At-t-he rein: of seid deck is pfovided an inolined driveway, (indioated es a whole by,) whioh leads upwardly to alle decking of tl1e frame and adn1its of driving the front wheels of a Wagon thereon.

Rigidly bolted- 110 each of the sills A and A and braoed byrods a and angle-lmrs a thereto are A-r'remes, of angle-iron, comprieing tl1e upwardly-directed converging side 1110111be1s B and B, which a1e rigicfly secured together et tl1e top by means of a honsing orband b, ol metal, l ent mound seid angle-iron up1ights and rigidly bolted thereto, als shown in Figs. 1 and 2. J ournaled in th e top of seid A-lmn1o upon a bolt b, passing through the sides ol' seid band o1 housing Z), is the sheave Z Supported nonnally on tl1e joists 01' transverse members ol the deck is a cmriago comprising parallel front und I'dl' membersC und C, connected al; tlxeir ends by angle-burs Fig'. 13 is a sec- Gulden. comonient'ly 1dly bolted to the anglG-bars c a1: an inclination o correspond With the i1iclination of the sides 0f the A-frame, so tha t as the carriage is elevated it is .guid6d thereby 0bliquely upward and rearwardly.

Hoistingchains are connected at one end to Gach ei1d 01 the carriage at the middle of the transverse angle-bars c 0f the carriage and extend upwardly over the sheaves b 130 winches carried on each end 0f a winch-shaft D. Said winch-shaft isjournaled 011 said sills and if preferred, on one 01 more of the transverse joists o1 supporting members by means admitoing lorig1tudinal mnvement 0f said shaft. The drive end of said shaft ex tends through a frame-plate d, rigidly bolted 130 said sill A, between which and said l'1ameplate a gear-wheel d, whereby power is communioared to said shaft is rotatively secured on said shaft and is held from slidin with the shaft by the brackets d, which are olted t0 the frame-plate d apnd engage over the geard, as shown in Figs. 6 and 17. end D of said gear-wheel is shaped to form a clutch member. The drum d is ri idly secured 011 said shaft D and at its end l) adjacent the hub end D ol" said gear-wheel is A shaped complemental and adapted to engage therewith, as shown in Fig. 5. Said end D 0l said drum is of larger diamiater than 'the drun1 proper, and the face thereof adja.cent

the drum is shaped 130 conform with the thread of the chain around the drum and acts to guide a chain or the like thereon. \Said drum may be secured in any desired mannr on the shaft. As shown, however, a bolt (Z extcnds therethrough and into the shaft, whicl1 isseated to receive the end thereof, and said l) )lf; is held in positionby means 0f a nut d, positioned between the shaft andthedrum.

' th.ereun.

Tlw end of the hoisting-chain is secured 011 suid holt d. A5 shovvn, a correspo'ndingbolt d" is socured ner the inner end of the drurn ancl likcwise ab its inner end seated in the shalt und hold in position by a nut d". The outor end of said holt exi;ends out wardly from the drum and act's fio guide the chain At oho other end 0f said Winchslml't is yirovided a drum d, corresponding With that driven by the gear d and similarly secu1ed upon the sl1 aft by means 0f bolts dd. Said drum. d is pfovided' at its 011ter, end with an integral concave friction-disk d, which afi"ords aconical inner bearing-surface an d adapted for engagement with the male c0nical friction member D, through Which said winch-shaft passes, as shown in F igs. 1 smd 7, and which isnon-rotatively secured upon the sill A by means of a bracket d, which extends do wn on tihe immer side of said sill and is rigidly seCured thereto byabolt d.

- Ablock d is also engaged 011 tl1e outer side 0l The inner hub the end of ;-lihilShft D, asshown in Figs. 1 and 8; by meansof a, sleevef, which fits upon thga end of said shaft zmd in which said shaft rotates and which is held from movement longitudinally ofthe shaft by pins f rigidly secured in sa1d 'sleeve and Which project into a peripheral groove in the end of said shaft, so tha when said lever ismoved inwardly toward the platform 01 deck the clutch a1; the power end of the shaft engages, commum'cating the rotation of said ge'a1 d thereto and elevating the carriage'. Outward movement of the lever draws the clutch out of enga ement and piarmits the shaft t0 reverse un er the Weight 0f the carriage and load thereon, tl1e friction-b1ake heretofore described serving t0 control said d0wnward movement. The gear d 011 the end of said'sb ft may 0bviously be acfiuated in a variety ofways. As shown, how ever, a snail-gear G is rigidly secured on'the inner end of a main drivingshaft' E,Which, as shown, is j ournaled in the framelate d at s right angle with thewinch shafli Saicl main sh2aft E extends rear- War-dlj and is' coni1ected With a tumbling-rod 01 o'bhe1 driving'shaft E by means of a coupling p1ovioled with an angular axial aparture at o'ne end t0 receive said tumbling-rod and at Qheother end provided With a cylindric aperture 130 receive th'e'main shaft E and shaped afio rd a clutch member adapted for engagenqent with the complemehtal end of a sleevee, feathered on said shaft E and which is p'fovided with a central circumferential groove as shown in Figs. 3 and 4, in which.engage pins e, rigidly secured in a yoke e, nesir lbhe middle ofthe adjust'ing-lever E Said'lever, as shown, is pivote"d 011 the sill member A, and when swun'g toward the A jfiame acts t0 disconnect said clutch memb ers als the coupling and when 'swung oppositely therefrom throw be same into engagement. As show1i, said coupling is cylind1ic an'cl provided W1'th er1pheral end flanges e e, and a bar e is rig1dl scu red on said sill and at its end is prov1de with an upwardly-ezgbending stop e", which engages between said flanges and receives .the thrust "0f tl'1e lever When said clptchengages. M;eans are provided f0r actuatifig said lever automatically, corhprising a chain e, connected therewith, Wh1ch leads therel'rom over a sheave e pivoted 011 the leg-B of the A frame and the end ofwhich extends downwardly from said sheave and is' connected With a trigger-plate e, which is also pivoted on said leg 0f the frarne and is directed 1'11- wardly toward the path 0f the chain b, Which, as shown in Figs. 2, 14, and 15, is provlded With angular brackets b", bo lted through 0ne ol the links thereuf, and Whi0h project outwardly i11t0 position to engage said trigger-plate, therelwy tripping the lever E and disconnecting the coupling, thereby stopping the upward elevation of the carriage.
